A matrix with ATAC-seq counts in select peak regions from chromosome 1 for 37 patients.

Each row corresponds to one region and the coordinates for these regions are in the object brcaATACCoord1, (data("brcaATACCoord1"), hg38 genome). Only select regions on chr1 are included to keep the example data small. Columns are patients, with TCGA patient identifiers as column names. 4053 regions are included. ATAC-seq data is from breast cancer patients from The Cancer Genome Atlas (TCGA-BRCA, Corces et. al, 2018, doi: 10.1126/science.aav1898, https://atacseq.xenahubs.net/download/brca/brca_peak_Log2Counts_dedup).
